The Prospero project explores the use of a conversational agent and investigates what is the most suitable occasion for delivering memory training. With the hypothesis that users are more likely to accept prompts for memory training when they are not busy, we used physiological sensors to monitor the user's cognitive load and issue prompts only when the cognitive load is low. Further studies are being conducted to test our hypothesis and evaluate the system.
